Groundwater lowering in construction: A practical guide to dewatering 3rd edition
By Pat M. Cashman and Martin Preene

This third edition of Groundwater lowering in construction has been extensively revised from previous editions, with considerable quantities of new material.

To aid the reader, the main text is essentially divided into three sections – Principles, Design and Construction.

The Principles section covers the fundamentals of groundwater flow as it relates to civil engineering excavations.

The digital revolution has not changed the basic principles, and even now that sophisticated numerical modelling tools are widely available, going back to Darcy’s law and the concept of permeability can be illuminating, even with complex problems.

Groundwater lowering in construction: The Design section includes a general broadening of coverage from previous editions, including much more detail on groundwater control for tunnelling projects (including shafts and cross passages) and on permeability assessment methods.

The chapters on Construction include the complete life cycle of a groundwater control scheme, including monitoring, maintenance and decommissioning. This section includes 11 case histories from the Cashman and Preene casebook.

Finally, I would like to reiterate that, true to Pat Cashman’s intent when he started writing nearly 30 years ago, this third edition is intended to be a practical book.

While much theory and analysis will be found herein, I hope the advice and experience distilled here is of some help when trying to control groundwater out there in the field.
